The new edition of Wissenschaft weltoffen was published last week. For two decades, Dr Ulrich Heublein from the German Centre for Higher Education Research and Science Studies (DZHW) was one of the main authors of the publication, which is jointly published by the DAAD and the DZHW. In our interview, he talks about its key findings and explains the content and function of the new chapter on structural aspects of internationalisation. He also takes a look back at the last 20 years of university internationalisation and ventures a look ahead to the next 20 years.
